Answer:

m=-5/2

Step-by-step explanation:

Two points on the line are (-2, 1) and (0, -4).

So, we have to use the expression Δy/Δx to find the slope.

So, (1-(-4))/(-2-0)=5/-2=-5/2.

Write an equation if the line that is parallel to y=2x-5 and passes through (-4,2)
Leokris [45]

Answer:

Step-by-step explanation:

y=2x-5

From y=mx+c

Comparing the equation

M=2.

For parallelism

M₁=M₂

y-y₁=m(x-x₁) equation of a line passing through a point

point (-4,2) are x₁ and y₁ respectively

y-2=2(x-(-4))

y-2=2(x+4)

y-2=2x+8

y=2x+8+2

y=2x+10

Which equation can be used to describe the direct variation function between E, the total earnings in dollars, and h, the number
kipiarov [429]

Let us take a sharp point for the graph.

In 4 hours total earning is $30.

Therefore, earnings per hours would be 30/4 = $7.5 per hour.

Are given direct variation between Total earnings(E) and Number of hours worked(h).

So, we can setup a direct variation as

Total earnings = Earning each hour * Number of hours.

Therefore, direct variation function would be

E=7.5*h.

Therefore, the direct variation function between E, the total earnings in dollars, and h, the number of hours worked is E = 7.5h.

Find the asymptotes of the hyperbola described by the equation: y2/9 - x^2/81=1. ANSWERS ATTACHED, due in 2 HOURS, will give Bra
Kisachek [45]

Answer:

Solution : y = ± 1/3x

Step-by-step explanation:

Remember that the equation of a hyperbola is in the form (y - k)² / a² - (x - h)² / b² = 1. Therefore we have a² here = 9, and b² here = 81.

To determine the asymptotes we can use the equation y = k ± a/b(x - h). What makes this equation really simple, is that k = 0 and h = 0, giving us y = ± a/b(x). Let's isolate a and b given a² = 9, and b² = 81 --- (1)

a² = 9

a = 3

b² = 81

b = 9

Therefore our asymptotes will be in the form y = ± a/b(x) = ± 3/9(x) = ± 1/3x. Our solution is thus option a.

Simplify.<br><br> n 6 · n 5 ÷ n 4 · n 3 ÷ n 2 · n
trasher [3.6K]

Answer: n^{9}

Step-by-step explanation:

Given expression: n^6\cdot n^5\div n^4\cdot n^3\div n^2\cdot n

The law of exponents are given by :_

a^m\cdot a^n=a^{m+n}\\\\a^m\div a^n=a^{m-n}

Using PEDMAS, first we solve division, we get

n^6\cdot n^{5-4}\cdot n^{3-2}\cdot n\\\\=n^6\cdot n\cdot n\cdot n

Now, using product law of exponent we get

n^{6+1+1+1}\\\\=n^{9}
